Adapting overhead lines in response to increasing temperatures in UK

Several energy transmission and distribution companies in the UK have begun to take the impact of increasing temperatures into consideration for the long-design of electricity distribution infrastructure. Rising temperatures can impact power lines by reducing their thermal rating (i.e. the maximum current allowed at a given temperature) and causing lines to sag to dangerous levels.

Replacing overhead lines with underground cables in Finland

This case study considers a Finnish example of replacing overhead lines with underground cabling. The same strategy is also applied in other European countries. Elenia is the second largest electricity distribution system operator in Finland. To adhere to the outage requirements of Finland’s updated Electricity Market Act, distribution system operators such as Elenia are investing substantially in underground cabling.

Hydropower expansion and improved management in response to increased glacier melt in Iceland

Iceland has 100% renewable electricity and heat system due to its abundant hydro- and geothermal resources. Despite the clear dominance of geothermal resources for house heating, hydropower plays an important role in Iceland’s energy mix, enabling Iceland’s electricity generation to be 100% renewable with 73% coming from hydro; 27% from geothermal and less than 0.01% from wind. The biggest hydroelectric power stations in Iceland are fed by glacial rivers.

Operation of the Portuguese Contingency Heatwaves Plan

Evidence that elevated temperatures can lead to increased mortality and morbidity is well documented, with population vulnerability being location specific. The elderly are particular vulnerable to extreme heat stress. Being part of the Iberian Peninsula, Portugal has a mild Mediterranean climate. Climate change projections indicate that the number of days with extreme heat in Portugal will increase with urban areas being more sensitive.

Operation of the Austrian Heat Protection Plan

Evidence that increasing temperatures leads to increased mortality and morbidity is well documented, with population vulnerability being location specific. Especially the 2003 heat wave in Europe raised the awareness of negative impacts of heat stress on human health in Austria. Increased incidence of heat waves leads to an increase in heat stress, especially in urban areas; the intensification of the heat-island effect is to be expected.

Adaptation of French standards for design, maintenance and operation of transport infrastructures

At the request of the Ministry of Ecology, Sustainable Development and Energy (DGITM), Cerema (Centre d’Études et d’Expertise sur les Risques, l’Environnement, la Mobilité et l’Aménagement) under supervision of the French Administration, completed in 2015 a systematic review of standards and guidelines on the design, maintenance and operation of transport infrastructures. The aim of this review was to adapt transport infrastructures and systems to future climate conditions and foster greater resilience to the effects of extreme weather events.

Implementing climate change allowances in drainage standards across the UK railway network

The UK is generally projected to experience increases in extremes of the precipitation regime as a result of climate change, especially in terms of higher occurrence and intensity of heavy summer rainfall events. An important resilience action to mitigate the impacts from such increases is the improvement of drainage management. Climate change resilience within Network Rail, the national railway infrastructure managing authority in Great Britain, is driven by corporate strategic objectives defined by the Weather Resilience and Climate Change Adaptation Strategy (WRCCA), finalized in 2017.

IRRINET: IT irrigation system for agricultural water management in Emilia-Romagna, Italy

IRRINET is an IT irrigation system aiming to advise farmers on efficient water management. This web service was developed with public funding by the CER (Canale Emiliano Romagnolo, a water consortium located in the Emilia-Romagna region) based on a 1984 project which tested the use of telematics tools in agriculture in Emilia-Romagna. In 1999, with the arrival of Internet, IRRINET started to be developed in a web form and is still active and operative in this Italian region.
